The three parties who have made bids for Rangers are still interested in buying the club, but want clarification from the Scottish Premier League over proposed rule changes.
One amendment would see clubs hit with a 10-point penalty for two consecutive seasons if they establish themselves as a new company.
League payments could also be cut by 75% for three seasons.
"Following discussions with three parties bidding to purchase the football club, we can confirm that all three parties have informed us today they wish to remain in the sale process," said joint administrator Paul Clark.
"However, following the information supplied by us to bidders in relation to proposed new rules on penalties for insolvent clubs within the SPL, there have been changes made to the conditions attached to bids.
"Among the new conditions are requests from parties who now, before committing further, wish access to the football authorities in order to seek greater clarity on the proposed rule changes."
SPL clubs will vote on the proposed changes on Monday, April 30.
